a friend he said it was pi/2, i guess he was wrong because i see now way of getting that, well for these problems like the one above i just get trig function inside the para and thats the awnser. Can i make that generalization?

oh, and thxs for the help

No. What's the domain for the arcsin function? A function only has one possible y (range) for any given value of x (domain).

0 is not the final answer (the quoted post suggests you know that). Instead you have to find a value within the domain of the arcsin function that has a sine of 0.

The variation is if, instead of asking the arcsine, the question asks for all possible values for [tex]\theta[/tex] that have some given value for sine.
